If you’re at all curious to see what might happen were the new-for-2018 Chevrolet Tahoe RST to go head-to-head against the 2018 GMC Yukon XL Denali, this video is for you.

As the guys from TFLnow point out, both of the SUVs featured in this video are powered by GM’s 6.2L L86 V8 engine, which turns out 420 horsepower and 460 pound-feet of torque, backed by a 10-speed automatic transmission. Both SUVs weigh well over 5,000 pounds, but being an XL, the Yukon is a bit heavier than the Tahoe.

In instrumented testing, the Tahoe RST has proven capable of a sub-six-second sprint to 60 mph.

No one can say that isn’t fast, but for those who desire even more ludicrous speed out of a GM SUV, the aftermarket can provide. Hennessey’s beastly HPE650 Yukon XL, for instance, churns out 650 peak horsepower with its supercharged, 5.3L L83 V8 – plenty enough to get the big, heavy brute moving with gusto.

This video isn’t about modified SUVs, though; it’s about which of these nearly-identical, factory-stock GM SUVs is quicker in a straight line. Of course, a rudimentary understanding of the laws of physics is enough to tell you which will win, but there’s still the question of how great the gap will be.

GM trying to market RST sothey had to make it look good against the already popular Denali by putting the heavier XL Denali against regular size Tahoe.. should have both been the regular size models..
Denali lineup should have a Denali -R addition, comparable to what an Escalade-V series would be!!
